產(chǎn)品說明:
熱塑性彈性體（TPE）系列中一種柔軟、可著色的特種熱塑性硫化膠（TPV）。它符合食品及藥物管理局（FDA）對(duì)重復(fù)使用的橡膠制品以及與非脂肪、非油性食品接觸的橡膠制品的規(guī)定，如封口和密封墊圈。這種等級(jí)的Santoprene TPV是剪切依賴的，可以在常規(guī)熱塑性塑料設(shè)備上進(jìn)行注塑或擠出加工。它是聚烯烴為基礎(chǔ)，完全可回收。
A soft, colorable, specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It complies with FDA regulations for rubber articles intended for repeated use, as well as those in contact with non-fatty, non-oily foods as closures and sealing gaskets. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding or extrusion. It is polyolefin based and completely recyclable.
